Herdline

The milk register says what each cow gave. The wall calendar says when she was served. Neither tells you the two numbers that decide whether a dairy makes money. Herdline keeps both books in one place and works those numbers out for you — completely offline, with no account and no subscription. MILK, THE WAY YOU ACTUALLY RECORD IT • Enter the whole parlour in one pass — morning, midday and evening • A running total as you type, so you catch a mis-keyed figure on the spot • Per-cow daily log and a lactation curve built from it • Days in milk, 305-day yield, total yield, peak yield and the day it fell on THE BREEDING CALENDAR THAT WORKS ITSELF OUT • Log a heat, a service, a pregnancy check, a calving or a dry-off • From one service Herdline derives the pregnancy-check date, the expected calving 283 days on, and the suggested dry-off • Calving interval computed from the last two calvings, per cow and herd-wide • A missed heat costs a full 21-day cycle — the Today board is how you stop losing them TODAY / UPCOMING — ONE DATED LIST • Heat checks, pregnancy checks, expected calvings, dry-off, vaccinations and deworming • Milk-withdrawal windows shown right on the milk-entry screen, so treated cows are impossible to miss • In-app only. Herdline sends no push notifications and asks for no notification permission INSIGHTS COMPUTED ON YOUR PHONE • Herd yield over 7, 30 or 90 days as a chart • Top and bottom producers, ranked, with litres per day • Feed cost against milk value, and the net margin • Cost per litre — the figure that decides profit • Herd composition at a glance: milking, dry, pregnant, heifers THE FEED AND MILK LEDGER • Record feed purchases and milk dispatches with quantity and rate • Fat and SNF when the dairy reports them • A running margin. Herdline records amounts — it moves no money and connects to no bank HEALTH RECORDS, NOT MEDICAL ADVICE • Vaccinations, deworming, treatments, hoof care and check-ups • The milk-withdrawal date your vet set, tracked to the day • Next-due dates that surface on the Today board • Herdline suggests no treatment, no dosage and no withdrawal period, and makes no diagnosis FIND ANYTHING, ORGANISE EVERYTHING • Full-text search across cows, treatments, ledger entries and breeding events • Filter by status, breed or shed; sort by name, tag, age or recency • Tags, sheds and pinned cows on your dashboard • Multi-select for bulk actions; sold and culled cows archive with their history intact • Undo on every deletion STREAKS, GOALS AND MILESTONES • A recording streak that means something — a missed day is a real gap in the ledger • Targets for daily herd yield, cost per litre and calving interval, with progress rings • Milestones that unlock from real husbandry: first calving logged, a cow past 25 L in a day, a calving interval under 400 days, a 1000 L month YOURS, AND ONLY YOURS • Records stored encrypted on this device with AES-256 • Full JSON backup you can restore from, plus CSV for every entity • Send a backup wherever you keep it, using the Android share sheet • Theme, accent colour and row density are yours to set WHAT HERDLINE DOES NOT DO • No account, no sign-up, no cloud sync • No advertising, no analytics, no third-party SDKs • No in-app purchases and no subscription — the app is free • One permission, INTERNET, used solely to open the privacy policy inside Settings Built for owner-operators running five to sixty cows, in sheds where the signal does not reach.
